SAN DIEGO, July 31, 2025 (GLOBE NEWSWIRE) -- LENZ Therapeutics, Inc. (Nasdaq: LENZ or “LENZ” or the “Company”), today announced the US Food and Drug Administration (“FDA”) approved VIZZ (aceclidine ophthalmic solution) 1.44%, the first and only FDA-approved aceclidine-based eye drop for the treatment of presbyopia in adults. Samples are anticipated in the United States as early as October 2025, with commercial product to be broadly available by mid-Q4 2025. Direct-to-eye care professional sales and marketing activities to be initiated immediately.
“The FDA approval of VIZZ is a defining moment for LENZ and represents a transformative improvement in the available treatment options for the 128 million adults living with blurry near vision in the United States. We are ready and excited to launch the first and only once-daily eye drop with proven efficacy for up to 10 hours into the market,” said Eef Schimmelpennink, President and Chief Executive Officer of LENZ Therapeutics. “This significant milestone is the result of tremendous commitment and collaboration by the LENZ team and our partners, the dedication of our clinical investigators, and the contributions of hundreds of participants in our clinical trials. I want to thank each of them for their role in getting VIZZ FDA approved.”
VIZZ is powered by aceclidine, highlighted by its differentiated mechanism of action as a predominantly pupil-selective miotic that interacts with the iris, with minimal ciliary muscle stimulation. VIZZ contracts the iris sphincter muscle resulting in a pinhole effect and uniquely achieves a sub-2mm pupil that extends depth of focus to significantly improve near vision without causing a myopic shift. Aceclidine, the sole active ingredient in VIZZ, is a new chemical entity in the United States and its FDA approval marks a global first in the treatment of presbyopia.
“This FDA approval represents a disruptive paradigm shift in treatment options for millions of people who are frustrated and struggling with the inevitable age-related loss of their near vision,” said VIZZ clinical investigator Marc Bloomenstein, OD, FAAO, of Schwartz Laser Eye Care Center in Scottsdale, Arizona. “I believe this will be a welcome solution for both optometrists and ophthalmologists who will now be able to offer a highly effective and sought-after presbyopia treatment that could immediately become the standard of care, with a product profile that will meet our patients’ needs.”
The FDA approval of VIZZ was based upon results from three randomized, double-masked, controlled Phase 3 studies. CLARITY 1 and CLARITY 2 were designed to evaluate the safety and efficacy of VIZZ in 466 participants dosed once daily for 42 days. CLARITY 3 evaluated 217 participants for long term safety over a 6-month duration of once daily dosing.
In both CLARITY 1 and CLARITY 2, VIZZ achieved all primary and secondary near vision improvement endpoints, demonstrating the ability to improve near vision within 30 minutes and last up to 10 hours. Near vision improvement was reproducible and consistent across both CLARITY 1 and 2. VIZZ was well-tolerated with no serious treatment-related adverse events observed in the over 30,000 treatment days across all three CLARITY trials. The most common reported adverse reactions of participants were installation site irritation, dim vision and headache. The majority of adverse reactions were mild, transient and self-resolving.

About Presbyopia
Presbyopia is the inevitable loss of near vision associated with aging. It impacts the daily lives of nearly all people over the age of 45. As people age, the crystalline lens in their eyes gradually hardens and becomes less able to change shape. This loss of elasticity of the lens reduces the ability of the lens to focus incoming light from near objects onto the retina. Adults over age 50 lose, on average, 1.5 lines of near vision every six years. Although the progression of presbyopia is gradual, presbyopes often experience an abrupt change in their daily life as the symptoms become more pronounced starting in their mid-40s, when reading glasses or other corrective aids are suddenly necessary to read text or conduct close-up work. Presbyopia is typically self-diagnosed and self-managed with over-the-counter reading glasses, or managed, after evaluation by an ECP, with prescription reading or bifocal glasses or multifocal contact lenses.
